In an effort to deploy next-generationservices while leveraging the existing network infrastructures, carriers are looking for solutions that control cost, promote efficiency, and simplify operations.The ADTRAN® Total

Access® 1248 is atemperature-hardenedDSLAM that enables delivery of up to 48 ports of POTS and ADSL/ADSL2/ADSL2+ from smaller central offices, controlled environmental vaults, multiple dwelling units, and remote terminals.

The ADSL/ADSL2/ADSL2+ is generated locally and placed, via onboard splitters, on the same pair as the corresponding POTS signal for delivery to the customer. The

Total Access 1248 to be mounted as a rack, wall, or vertical positioned unit inside the RT. It measures 1.75 in. H x 17.25 in.

W x 11.125 in. D and offers redundant power using -42to-56VDC.

Two different models of the 1248 MiniDSLAM are available: one with a fixed 10/100/1000Base-Tcopper Gigabit Ethernet interface or an SFP module interface accepting copper or 1000Base-Xfiber SFP modules. The IPMini-DSLAMsalso incorporate a wide array oftriple-playenabling

Intermediate Agent. With a standard Gigabit Ethernet interface, the unit is interoperable with any Gigabit Ethernet aggregation switch or router. The Gigabit Ethernet uplink provides a non-blockingarchitecture to ensure adequate bandwidth for next generation services.

Developed with concern for carrier field needs, the Total Access 1248 has pre-installedfan modules complete with fan filters. Each fan module and fan filter is independentlyfield-replaceable.The fans are controlled byheat-sensingcircuits and will run only when necessary. Front panel access is available

for all connections.

Management is made simple and convenient through a choice of SNMP, ASCII, TL1, or 10Base-TEthernet support. Provisioning, alarms, and performance monitoring are provided through the local craft interface and IPin-bandmanagement channel.
